摘要： A power seeder may include a frame, one or more wheels, one or more blades capable of cutting into soil, an engine capable of powering the one or more blades, and a seed hopper. The seed hopper may have an opening capable of dispensing seed located forward of the one or more blades. The one or more blades may rotate in an opposite direction to a forward rotation of the one or more wheels. In some embodiments, the seeder may further include a handle for adjusting the height of the one or more blades, a plurality of interlocking teeth, and a spring. The spring may provide a load to counteract the force of gravity on the one or more blades. The aerator may also include a flap located between the opening and the one or more blades.

摘要： The wheelbarrow of the present embodiments provides a frame and a tub wherein the tub has a recess for receiving at least a portion of a wheel. Additionally, at least a portion of the frame and a portion of the tub may extend forward of the wheel. Further, a distance between a center of gravity of the tub and a vertical line or plane bisecting a rotational axis of the wheel when the wheelbarrow is in a resting position may be approximately equal to or less than a radius of the wheel. Also, the wheelbarrow may be powered by an engine or motor. The wheelbarrow may also include a transmission capable of rotating the wheel in a forward or reverse direction. Moreover, the wheelbarrow may contain control levers located adjacent handle grips for controlling the motor or engine, or the transmission.
